1099 Contractor in Tennessee with a Connecticut Client: Where Do You File?
Answer
Usually nothing is due anywhere. As a Tennessee resident you file no state return, and Connecticut reaches only the part of your self-employment income that comes from work physically done inside Connecticut. Keep a record of any days you spend working on Connecticut soil.

The most common contractor worry — that invoicing an out-of-state client creates a filing obligation there — is usually unfounded. What creates the obligation is physical presence, and Tennessee residents have no home-state return in any case.
Connecticut publishes no de minimis day count or dollar floor for nonresidents. Any Connecticut-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the Connecticut Department of Revenue Services nonresident instructions before filing.

Questions people actually ask
I live in Tennessee and my client is in Connecticut. Do I have to file a Connecticut tax return?
Usually nothing is due anywhere. As a Tennessee resident you file no state return, and Connecticut reaches only the part of your self-employment income that comes from work physically done inside Connecticut. Keep a record of any days you spend working on Connecticut soil.
Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether Tennessee and Connecticut hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
